[6.5 forever]

Yes they should be using 41’s

I also used CCI450 when I shot ARs.

When they have to start replacing firing pins and bolts, that will get their attention. Add Winchester to that too! I learned the hard way!

How about the Winchester 41’s, will they pass in the AR’s?

 

[Kracken McGraw]

Awesome info guys, thanks.

Have a line on some 400s and/or 7 1/2s. Can buy the whole lot, all of the 400s or all of the 7 1/2s but not some of both to try.

Appreciate the replies, Matt.

The 7 1/2 would be the safe bet then.

Not shooting an AR dunno.

Buy those 7.5's, in the long haul with many cartridges, especially higher pressure ones, you will never be sorry.

Not sure if they are different. When Winchester primers cost me a couple firing pins, a bolt and issues in the P-100 at Perry, I walked away from Winchester and never looked back. I have used Russian SRM and Rem 7 1/2 since with no issues.

I just loaded some up and if they give any problems I’ll report back. Academy has them and can order just a thousand at a time with no Haz.

I hope so. They are built to the same spec as CCI 41's.

 

[Bill K]

Didn't CCI make the # 41's for Winchester and just package them with Win's name ?

I hope so. They are built to the same spec as CCI 41's.

I read it on the internet, so it must be true.
When I started fooling with a 17 Remington, I recall someone in an article said the 71/2 became because of the 17 Remington.
71/2’s can be hard to find at times, probably easier than preinterweb days. I got really low on 71/2’s, bought some CCI450’s, no issue with them.
I ran some 400’s in 204R and had some “issues”. Found out I had some excessive firing pin protrusion, that along with thin or soft cups of the 400’s.
All I run in my BR’s are 450’s, 6mm,22 and 20, no issues.
Have enough 400’s for a long while, I use them in 223 bolt guns with no problem.
Just my .02

The anvil is the only difference if I remember correctly between the two

41 primers are supposed to have the anvil set shallower so it does not slam fire with the floating firing pin on military guns. They also use a thicker cup to handle higher psi. CCI 450 is pretty much a 41 primer. I have been having my most accurate loads come from Rem 7.5br primers. I used to use a lot of cci 400 primers in my 223 bolt gun but I had the bolt head bushed and firing pin matched to it. But I also never ran it hot either.

My Savage 223 bolt would blank any primer that was not a 41 or cci450. When I replaced the barrel I also had the bolthead fixed so I had more available options than just the 41 and 450 primers. No I run mostly whatever is cheapest. I just shoot clay birds out to 500yds and I don't need the real good stuff using the components I now use. If I was shooting past that you bet ya I would be using and paying WAY more attention to what I load.

100% spot on Murray!….This makes me happy that someone besides myself knows what a 400 primer is for.
Wayne

I remember being challenged when i said it out loud here.

 

[jimmymac]

I shot a full season of BR with 400’s in both a PPC and a 30BR. Never had an issue.

 

[laangler]

I’ve been shooting cci 400 primers in my Savage model 10 223 for many years and never one problem any weather conditions
